Myosin V (green), a biomolecular motor that moves in nanometer-size steps on actin (red), transports cargo within cells. By placing a fluorophore near one foot (rainbow colored oval), and following the motion a single myosin V, Yildiz and others were able to determine that myosin V "walks," placing one foot over the other, and does not "crawl."
